One of the bigger mysteries of the last decade of country music is why Kristen Hall left Sugarland when the then-trio seemed to be on the brink of superstardom.
On Aug. 13, 2011, the stage collapsed at the Indiana State Fair moments before Sugarland were scheduled to perform, resulting in seven fatalities and dozens of injuries.
Country music may be known for its "tear in my beer" sad songs, not to mention its tunes about trucks, dirt roads and Southern living, but the genre also has a helluva sense of humor.
